Background technique
At present, the automobile silicon oil filled fan clutch that uses, its inside is divided into two chambers---working room and reservoir compartment, be usually said two section type silicon oil filled fan clutch, it is converted into the hot load state of motor by the bimetal temp-sensitive apparatus and rotatablely moves, when engine load is heavy, drive the valve block rotation with valve open, silicone oil is constantly circulated between working room and reservoir compartment, carry out high speed rotating thereby drive fan, it is cold moving that motor is in time obtained; And when engine load is light, with valve closing, the silicone oil of working room flow back into the reservoir compartment, the silicone oil of reservoir compartment no longer flows to the working room, drive fan and carry out low speed rotation this moment, play the state of balanced engine load, make motor be in preferable working state, with the working life of prolongation motor, but the silicon oil filled fan clutch of this type can only make rotation speed of the fan be at a high speed and the low speed two states, high, the low speed conversion is frequent, fan noise is big during high speed, and compares with the time of low speed at a high speed, and the high speed time scale is bigger, special in south and temperature higher season, to reducing noise and energy consumption significant limitation is arranged.
Summary of the invention
Goal of the invention of the present utility model provides a kind of adaptation in high, medium and low fast state work and can reduce fan noise and the three-segment type silicon oil fan clutch of the energy consumption in when work.
Three-segment type silicon oil fan clutch of the present utility model is to realize like this, it includes follower plate, protecgulum, active plate, bearing, driving shaft, housing, the bimetal temp-sensitive apparatus, valve block, bearing pin and silicone oil, it has driving shaft by bearing fixing in the middle of housing, settle active plate on the driving shaft, be fixed with the bimetal temp-sensitive apparatus at preceding exterior surface, control the working state of valve block by the riveted of bearing pin and valve block, master on valve block and the follower plate, secondary oil outlet opens and closes cooperation, follower plate is arranged on protecgulum and housing faying surface position, by screw on protecgulum, it is characterized in that, follower plate is provided with maze trough, cavity between protecgulum and the housing is divided into reservoir compartment in the protecgulum and the main working room in the housing of back, the subtask chamber, main working room is communicated with reservoir compartment in the protecgulum by the main oil outlet on the follower plate, and the subtask chamber is communicated with reservoir compartment in the protecgulum by the secondary oil outlet on the follower plate.
Described active plate is being provided with maze trough with the follower plate opposite position, is combined into labyrinth channel with maze trough on the follower plate.Its labyrinth channel transmitting torque effect.
Its beneficial effect is, the utility model has adopted that cavity is designed to three chambers between protecgulum and housing---reservoir compartment, main working room, subtask chamber, promptly increased middle temperature engagement rotating speed, make silicon oil filled fan clutch be in the engagement of low speed or middling speed as far as possible and have only the only a few time period to be in high speed joggleword state, changed original high, low speed frequent transitions, make motor be in optimum Working, reach and reduce fan noise and energy consumption and prolong the motor purpose in working life.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated
With reference to the accompanying drawings shown in the 1-2, three-segment type silicon oil fan clutch of the present utility model, by follower plate 1, protecgulum 2, active plate 3, bearing 5, driving shaft 6, housing 7, bearing pin 10, bimetal temp-sensitive apparatus 13, valve block 14 and silicone oil are formed, its fixing upper bearing (metal) 5 in housing 7 intermediate bearing holes, driving shaft 6 and active plate 3 are installed on the bearing 5, and make driving shaft 6 top flange, subsequently stud bolt 15 is screwed in the housing 7, cap assembly before then assembling, earlier bearing pin 10 and valve block 14 are riveted together, pack in the groove of bearing pin 10 with O shape circle 11, then bearing pin 10 is pressed into the steel bushing 12 that is arranged in protecgulum steel bushing hole, it is middle on the position of pin shaft hole subsequently 13 spot welding of bimetal temp-sensitive apparatus to be installed in protecgulum 2, subsequently pack into protecgulum and adjust the appropriate location of follower plate 1, be fixed on the protecgulum and constitute a reservoir compartment 16 with screw, in reservoir compartment 16, inject quantitative silicone oil, and after embedding sealing gasket 8 in the protecgulum seal groove, preceding cap assembly and housing assembly are snapped together, fixed with band bullet pad plus screw.
Described follower plate as shown in Figure 2, it is provided with one group of master's oil outlet 19, one group of secondary oil outlet 20 and maze trough 22 and spill port 21, after current cap assembly and the housing assembly combination, by maze trough 22 cavity in the housing is divided into main working room 17, subtask chamber 18, main working room is by main oil outlet 19, the interior reservoir compartment 16 of main working room 17 and protecgulum is communicated with, by the main oil outlet 20 of pair subtask chamber 18 is communicated with reservoir compartment 16 in the protecgulum, maze trough 22 on the follower plate is corresponding with maze trough on the active plate, and the combination back constitutes labyrinth channel and is used for transmitting torque.
Its working principle is the temperature according to car radiator, adjust the silicone oil flowing state, be heated change to drive bearing pin and force valve block 14 to produce to rotatablely move by the bimetal temp-sensitive apparatus and control silicone oil and flow: 1, when the motor moderate duty, the bimetal temp-sensitive apparatus changes drive bearing pin 10 and valve block 14 generations is rotatablely moved the secondary oil outlet 20 that leaves on the follower plate 1, make secondary oil outlet 20 be in open state, silicone oil circulates between subtask chamber 18 and reservoir compartment 16, this moment, active plate 3 was in middle temperature engagement with housing 7, kept fan by the moment of torsion of labyrinth channel transmission and was in the middling speed state.2, when engine load is high, the bimetal temp-sensitive apparatus is out of shape by the radiator high temperature action, force the outstanding more valve block 14 that makes of bearing pin 10 to rotate the major and minor oil outlet that leaves on the follower plate 1, major and minor working room is communicated with the reservoir compartment and circulates, because the silicone oil flow increases, the transmitting torque that produces by labyrinth channel strengthens, and forces fan to improve rapidly, realizes cooling fast.3, when motor is in the light load state, radiator temperature reduces, the bimetal temp-sensitive apparatus recovers the home position, drive the bearing pin return, make valve block close major and minor oil outlet on the follower plate, and the silicone oil that remains in the major and minor working room flows back to the reservoir compartment by spill port 21 under centrifugal action, and this moment, fan carried out the low speed rotation state.
